Police said they are still trying to establish the cause of the blaze.

Kenyatta paid tribute to the victims as he vowed to ensure such a tragedy does not happen again.

“Prayer will be followed by action. We will support victims and their families. … We will fully investigate the cause of the fire. …,” he said in his statement.

“The national Government and Nairobi County will sit together for a full review of our emergency services, and our disaster preparedness. We owe the victims, and the people of Nairobi, a clear, credible plan to end these fires.”

Kenya’s Red Cross said it has set up a desk to help people search for loved ones and is also offering support services.
